Unsigned data type

what is meaning of unsigned data type

@ankit_verma
In the programming world, when we talk about unsigned data types , it doesn’t mean the type is invalid (as in an unsigned document). It simply means that the data type will only hold positive values: Negatives are not allowed to be stored in the data type .
dont forget to mark resolved if cleared :smiley:
